            |   | 3 | This represents the simplest basic topology comprising a point to point link (either infrastructure AP to client or peer to peer) with a configurable packet error rate for certain packet sizes |

            |   | 7 | The configurable PER (for a particular packet size) is obtained by introducing AWGN noise  | 
          
          
            |   | 8 | at preset power levels on the channel used by the link. |

            |   | 10 | In order to achieve this, the following steps are needed | 
          
          
            |   | 11 |  * Fix the packet size to X bytes. (where X ∈ (80, 512, 1024) bytes) | 
          
          
            |   | 12 |  * Fix the PHY rate to Y Mbps (where Y ∈ (6, 9, 12, 18, 24, 36, 48, 54) Mbps) | 
          
          
            |   | 13 |  * Cycle through the noise levels and measure the PER for the given packet size and PHY rate | 
          
          
            |   | 14 |  | 
          
          
            |   | 15 | From these experiments, a set of feasible PERs can be obtained for the available noise levels. |
